Atmospheric river sets up Friday before possible snow arrives in Portland this weekend
PORTLAND, Ore. (KOIN) — It’s the calm before the storm. Enjoy a few more days of sunshine before a rainy and cold pattern sets up in Portland this weekend.
Before we get into snow chances by the late weekend in Portland, a strong low system that’s coupled with a weak to moderate atmospheric river will bring widespread rain back to the valley.
Forecast models show around 0.75 inches of rainfall possible around the valley and Portland area with breezy winds as well. We could see wind gusts from the south up to 30 mph by Friday morning that’s paired with the rain.
Weekend Snow Chances
Snow in Portland still remains uncertain this weekend. Models cannot agree on just how cold Portland may get, or how low the snow level may fall. Temps are toggling in the low to mid-30s throughout the weekend into next weekend. They may spell out more of a foothill snow event, where mixed snow and rain showers fall and light accumulations will only be seen for elevations about 1,000 feet. There are few to no weather models that spell out a major, city-wide snowstorm in Portland.
